The strength of the plain concrete section is more than enough to carry the actual tension load. The stress from the tension load across the concrete section is around 64 psi. The uncracked strength of the conc. is over 350 psi. If I assume its cracked, and let the rebar take all the tension...
Thanks all. I guess I should not call it a "beam", as the axial tension force is much greater than the small bending moment. It would be more correct to call it a tension member with some small amount of bending moment.
I have a concrete "beam" with tension and bending. An engineer has suggested that I check that the axial tension force and bending moment are inside the P-M curve.
I am confused as I thought a P-M curve was for Compression and Bending.
Am I missing something? Do you understand what He is...
Thank youall for great responses. I used to have some computer software that I could use to model in this "frame" using node, member and load data.I wish I had it now.
Back in the late 1970's I did some related analysis and moment distribution on indeterminate frames but haven't run into much...
I am looking at a bowstring,steel,roof truss about 100 feet span supported on W8 columns at each end. The columns are about 15 feet long. The truss is about 2 feet deep where it connects to the columns and about 9 ft. deep at midspan. The truss connects to the inside flanges of the columns with...
